Carlo Francesco Maciachini (Italian pronunciation: [ˈkarlo franˈtʃesko matʃaˈkiːni]; sometimes spelled Maciacchini;[1] 2 April 1818 – 10 June 1899) was an Italian architect and restorer.[2] Born near Varese, he studied in Milan, where he also realized some of his most important works, most notably the Monumental Cemetery (1866). Other notable works of Maciachini are restorations of historic churches in several cities of northern Italy.
Along with Camillo Boito, Luca Beltrami, and Luigi Broggi, Maciachini is one of the prominent representatives of the eclectic period of Milanese architecture, sometimes referred to as "Milanese Eclecticism" (approx. 1860–1920).[3][4]
